Are you (stale Kingsmill white-bread) You are white because you are white bread and dry because you stale. You are not green because you are not mouldy nor black because burnt; you are only stale. You compete against Genius 'gluten free' bread.

$\begingroup$@balazs.com I think you should explain your answer more in general. I have seen multiple answers where you simply write it down without proper justification$\endgroup$

$\begingroup$But i cant explain it further, I thought it was a white and dry apple with no mold on it. But by the way, I think the "computer" tag should have been added, I particularly have nothing to do with computers, nor with mathematics, believe it or not.)It is not trivial... (Thats why, for example, I add "knowledge" tag to my own puzzles if serious non-trivial knowledge is required.) Just for the future.$\endgroup$

$\begingroup$An explanation means a line-by-line justification of why you think your answer is correct; otherwise it is more of a guess, or only partial match with the clues in the question. That's all I meant :)$\endgroup$
